           efi_runtime_lock, which should make the quirk nature obvious and
           maintain the general policy that the EFI lock (name...) isn't
           exposed to drivers.)
      
         - Our version of MAGA: Make a.out Great Again.

      Dmitry Torokhov authored
      Now that LEDs core allows "blocking" flavor of "set brightness" method we
      can use it and get rid of private work item. As a bonus, we are no longer
      forgetting to cancel it when we unbind the driver.

      powerpc/64s: Fix possible corruption on big endian due to pgd/pud_present() · a5800762
      Michael Ellerman authored
      In v4.20 we changed our pgd/pud_present() to check for _PAGE_PRESENT
      rather than just checking that the value is non-zero, e.g.:
      
        static inline int pgd_present(pgd_t pgd)
        {
       -       return !pgd_none(pgd);
       +       return (pgd_raw(pgd) & cpu_to_be64(_PAGE_PRESENT));
        }
      
      Unfortunately this is broken on big endian, as the result of the
      bitwise & is truncated to int, which is always zero because
      _PAGE_PRESENT is 0x8000000000000000ul. This means pgd_present() and
      pud_present() are always false at compile time, and the compiler
      elides the subsequent code.
      
      Remarkably with that bug present we are still able to boot and run
      with few noticeable effects. However under some work loads we are able
      to trigger a warning in the ext4 code:
      
        WARNING: CPU: 11 PID: 29593 at fs/ext4/inode.c:3927 .ext4_set_page_dirty+0x70/0xb0

         .__se_sys_munmap+0x14/0x30
         system_call+0x5c/0x70
      
      The fix is simple, we need to convert the result of the bitwise & to
      an int before returning it.
      
      Thanks to Erhard, Jan Kara and Aneesh for help with debugging.
